H frame rotten

95 WS 3.8 w/60000, just got back from my mechanic, oil change,and exhast leak fixed. He told me that the H frame or subframe I'm guessing, that holds the engine up is roted real bad on drivers side and needs to be replaced. What is the Ford part name on this item? I would like to use a salvage part if possible, but can't find that listed on any salvage drop downs. Also are they interchangable between years, or do I have to stick with a 95. Any help will be greatly appreciated as I would like to have this done as soon as possible. Seems like my bargain isn't such a bargain after all:crying:
Tahnks in advance
